My kids are used to compromising too, but that doesn’t mean they always like it. One accepted that her sister got to go to France on a school trip and she didn’t, but the non-traveler got to play a very expensive club sport that summer so it was not as if she was asked to empty her piggy bank for the good of the family with nothing in return. The traveling kid attends an OOS public which in the end costs more than the private school the second child attends. Second child is a little bitter that I don’t pay more for her, or at least give her the difference.
